The password rules itself is fine, but, it doesn't inform about the max length of the password. Their max length is 14 characters, so even if you enter a password of 42 chars, you can login with the first 14 of it. In this case, I changed my password to Super_l0ng_password_that_fits_all_criteria, and could login with Super_l0ng_pas

Answer form SAS customer service:

Hi, Thank you for your e-mail. Our website only takes 14 characters as a password, so somehow when you registered it took all 49. But since our website only asks for 14 characters anything after will be valid. I would advice you to change your password. Have a wonderful day.
